Personally, I don't see why an evaluation would be so bad. No one says you have to do what they recommend, or that you have to do it right away.
I also think that many children may enjoy and benefit from OT. OT for kids is play based. There are sensory things that may help his general well-being at school and at home that you can be taught.
In my area, many people would use the the Intermediate Unit (IU) or Early Intervention program to do such assessments when the child is not yet school aged. Sometimes, if the child qualifies, some or all of the treatments are free.
